PLAQUE.

SPECIFICATION forming part of Letters Patent No. 303,857, dated August19, 1884.

Application filed April 16, 1884.

5 the following is a full, clear, and exact descript-ion.

This invent-ion consists of a glass plaque having a transparent spot inthe center on which to mount a picture, the remainder of 10 the plaquebeing frosted or madein imitation of porcelain by grinding or otherwise,or by grinding and painting, all as hereinafter fully described, andpointed out in the claims.

Reference is to be had to the accompanying 15 drawings, lormingapart ofthis specification,

in which similar letters of reference indicate corresponding parts inall the figures.

Figure l is a front elevation of my new and improved plaque having apicture mounted Fig. 2 is a sectional elevation of the same, taken onthe line a of Fig. 1. Fig. 3 is a sectional elevation of one of my newplaques without picture or paint, and Fig. -t is a sectional elevationof the plaque, show- 2 ing it painted at the back.

The plaque A is made of glass, with the plain transparent spot a in thecenter, upon the back of which the picture B is mounted and held by asuitable backing, I), of cloth or 30 paper, pasted to the back of theplaque over the picture. The space 0, between the transparent spot a andthe edge of the plaque, is ground by preference upon the inner concavedsurface, to givcthis part of the plaquea frosted At the back of theplaque, covering the same space 0 that is opaque, the plaque may becoated with paint (No model.)

or any substance producing the desired effect, as indicated by the darklines at d, Fig. 4. In most cases the paint or substance will be white,which, together with the frosting produced by grinding the plaque, givesthe plaque avery soft and rich appearance resembling porcelain somewhat;and the picture B, being placed at the back of the plaque, upon thetransparent spot a in the center, the picturehas the appearance of beingpainted upon porcelain. By using paints of dili'ercnt color s variousbeautiful effects may be produced.

Instead ofi'rostingthe glass by grinding the surface of the glass, the.plaque might be roughened or rendered opaque or transparent in theprocess of manufacturing the plaques and not depart from the principleof my invention.

Having thus described my in ventioml claim as new and dcsi re to secureby Letters Patent 1. The glass plaque A, having the plain transparentspot a. in the center, and the frosted surface 0 on one of its facessurrounding the said transparent spot, substantially as shownanddescribed.

2. The plaque A, having an annular frosted or ground space, (2, andcentral transparent spot, a, upon which the picture Bis mounted, theback of the plaque being coated with paintor other substance to the edgeof the picture and covering the frosted portion, substan tially as shownand described.
